What do the warning colours mean?

Red warning

  • Dangerous weather is expected and, if you have not done so already, you should take action now to keep yourself and others safe from the impact of the severe weather.
  • It is very likely that there will be a risk to life, with substantial disruption to travel, energy supplies and possibly widespread damage to property and infrastructure.

Amber warning

  • There is an increased likelihood of impacts from severe weather, which could potentially disrupt your plans.
  • This means there is the possibility of travel delays, road and rail closures, power cuts and the potential risk to life and property.

Yellow warning

  • Yellow warnings can be issued for a range of weather situations.
  • It is important to read the content of yellow warnings to determine which weather situation is being covered by the warning.
